Evergreen International Airlines flew its final military flight Friday and all remaining aircraft are now parked.

Closure of the company -- originally scheduled for last Saturday, but denied as false rumor by founder Delford Smith – would end a storied, three-decade history for the airline whose baggage includes close ties with the CIA. Evergreen once operated a global fleet of Boeing 747 cargo jets, running round-the-world flights and keeping a plane on standby for secret U.S. military missions.

Several Evergreen companies founded and owned by Smith have been major Yamhill County employers, as have the 83-year-old’s nonprofits, which include a water park and an air-and-space museum. Managers say the attractions will remain open. But the Oregon Department of Justice is investigating them for alleged commingling of funds between Evergreen’s profit and nonprofit arms, and Smith may have put up some of the planes in the museum as collateral being claimed by creditors.
